LE5 Too Many Tracks Being Recorded Error

I’ve been recording and have got up to a total of 5 tracks on this song, doing one track at a time, and when I started to record the next one the sound keeps going on & off & then the error came up “Too many tracks being recorded at once”.

But I’m only recording one!

I’m using a Lexicon Omega, but I also have an Alpha, and even switching between the different input devices the error still comes up, also got the error message “USB Controller bandwidth exceeded”…

The PC is running on Windows XP with service pack 3, the processor is anCeleron R running at 2.6ghz, 2 gig of ram, and the hard drive is only 1/4 full. It’s not on the internet, but just being used for this job.

Any ideas or help please.
